I work in the medical industry and enjoy design & fabricating furniture. Maybe you could design and fabricate medical devices. 
I also sculpt. Most certainly a hack at that, but is a nice distraction.
Working the body definitely relaxes the mind. I ride a bicycle to that end. But I also find the history of bike racing interesting. So much so I have a credit on IMDB as an associate producer of a documentary about a long dead Italian racer. Top spot on my resume. 
Hopefully the bread-making will work for you. But if it doesn’t, don’t worry about any time or money invested, just move on to something else. I had tried a lot of things before the bike thing stuck.
